Tree nut immunotherapy

Multi-food OIT

Many people allergic to one nut are allergic to other nuts, and/or other foods.

Doing simultaneous OIT for multiple nuts makes sense in terms of the time/cost saving. Outcomes are pretty similar. The more foods, the more complicated – it also means a higher amount of maintenance

Obviously makes sense if younger age, lower IgE, higher reaction thresholds.

You need to think about what you are going to choose to treat, and what/if you need to challenge. Often some of the nut allergies come up on testing only and have never been eaten, so probably less important to challenge. You can always adjust the regimen to pause one food and continue another, if things are not going to plan. Most clinics just reduce both/all foods if there is a reaction, for simplicity.
